Definitions
- the present invention relates generally to a multipurpose electromechanical device which provides a pumping function such as might be required in an air conditioning system as well as an electrical energy generating function to obviate the need for, for example, a .[.separatively.]. .Iadd.separately .Iaddend.driven vehicle alternator.
- a prime mover such as an internal combustion engine, which in addition to supplying energy to drive the vehicle, also provides energy to a number of other devices through a maze of V-belts, pulleys and the like.
- an engine drives an electrical generator or alternator, a water pump, a power steering pump, an air conditioner pump or compressor, various anti-pollution devices and perhaps other devices.
- the typical alternator will be engine-driven by way of a V-belt and a relatively small diamater pulley, for example, of the order of 21/2 inches in diameter.
- the alternator typically therefor revolves at a relatively high speed generating a relatively high frequency alternating current voltage.
- stator core losses are relatively high and with such a small diameter pulley, belt slippage is a substantial problem. From at least a size standpoint, larger pulleys and lower frequencies have heretofore not been practical.
- Compressors for vehicle air conditioning systems are typically also belt-driven from the engine by way of a pulley, which is selectively coupled to the compressor shaft by an electromagnetic clutch arrangement. Much of the time this electromagnetic clutch is not actuated and the compressor pulley and V-belt are "free wheeling", contributing nothing to the system except frictional losses. As compared to an alternator, the current compressor design is of a lesser number of revolutions per minute, greater pulley diameter (a six inch diameter pulley would not be uncommon) and a somewhat larger overall structure. The larger pulley diameter and slower speed reduces belt slippage and related problems.
- the provision of a single electromechanical device which will supplant the typical vehicle generator and pump; the provision of a space, weight and cost saving arrangement wherein an alternator rotor is rotatably supported on the bearings required for a pump and the stator assembly is supported on the pump housing; the provision of an alternator function of reduced frictional and eddy current losses as compared to the above-mentioned alternator systems; and the provision of an electromechanical device which provides an alternator function while lessening the noise associated with prior art alternators due to belt slippage and high speed of operation or rapid acceleration.
- a combined pump and generator arrangement includes a pump housing with an axially extending actuating shaft, a rotatable member to be driven, for example, by a vehicle engine to rotate about the actuating shaft axis, a magnetic field arrangement on the rotatable member to provide a rotating magnetic field when that member is driven, and an annular stator assembly fastened to the pump housing and having windings for providing an electrical voltage in response to the rotating magnetic field.
- the actuating shaft and annnular stator assembly are concentrically disposed with the annular stator assembly lying intermediate or between the actuating shaft and the permanent magnet arrangement.
- a clutch may be provided selectively to couple and uncouple the rotatable member and the pump shaft; however, the generator is operative regardless of whether the clutch is engaged or not.
- a generator integral with, yet operating independently of, a pump may thereby .[.by.]. .Iadd.be .Iaddend.provided.
- a vehicle air conditioner compressor has a compressor shaft, a continuously driven flywheel which is selectively coupleable to the shaft to operate the compressor, and is capable of generating electrical energy in response to the flywheel rotation due to the provision of a permanent magnet field which rotates with the flywheel, and a relatively stationary annular stator assembly having windings for providing the electric voltage in response to the rotating magnetic field.
- FIG. 1 is a perspective view of an electromechanical device which embodies the present invention in one preferred form
- FIG. 2 is an exploded perspective view of the electromechanical device of FIG. 1;
- FIG. 3 is a side view partially in cross-section of the electromechanical device of FIG. 1;
- FIG. 4 is an electrical schematic diagram partially in block form illustrating one electrical arrangement for the alternator of the present invention.
- FIG. 5 is a side view partially in cross-section of a variation on the electromechanical device of the present invention.
- the prime mover such as an internal combustion engine
- Pulley 15 drives the alternator of the present invention whenever the engine is running, and when clutch arrangement 17 is actuated, also drives .[.in.]. .Iadd.an .Iaddend.air conditioner compressor 19.
- Three leads 20, 22 and 24 extend from Delta connected alternator phase windings and a clutch energizing or .[.controlled.]. .Iadd.control .Iaddend.lead 26 extends from a clutch actuating electromagnet to a thermostat or control switch 32 for clutch control.
- FIG. 1 illustrates a unified pump-generator structure and such a combined arrangement provides a compressor function for a vehicle air conditioning system as well as a generator or alternator function for supplying the vehicle electrical needs.
- FIGS. 2 and 3 The detailed construction and operation of such a combined arrangement will be most easily understood by considering FIGS. 2 and 3 together.
- the pump or compressor 19 has housing 21 from which there is axially extending a drivable compressor .Iadd.actuation shaft 23, rotation of which actuates the compressor .Iaddend.in a conventional manner.
- Housing 21 also has fixedly attached thereto an annular generator stator assembly 25 which comprises a slotted laminated magnetic core 27 having windings 29 disposed in the core slots.
- annular coil 31 which when energized creates a magnetic field to actuate clutch 17.
- Shaft 23 may be thought of as rotating about imaginary axis 33 and the annular coil 31 as well as the generator stator assembly 25 are attached to housing 21 concentric to one another and to axis 33. Similarly, these last two annular members are concentric with compressor crank shaft 23.
- Shaft 23 is fixed, for example, by key 35 in keyway 37, by threading, or both, to member 39. Such threaded attachment may be facilitated by nut 41 and threads 43 on the compressor crank shaft. Still further, fixedly connected to member 39 and spaced therefrom is clutch support plate 45. Clutch support plate 45 may be connected to member 39, for example, by bolts or rivets 47, and this bolt or rivet 47 may also affix one end of spring 49 to the clutch support plate. As illustrated three such springs 49 have their ends remote from the bolts or rivets 47 connected to clutch plate 51. If shaft 23 is rotationally motionless so are member 39, clutch support plate 45, leaf springs 49 and clutch plate 51.
- clutch plate 51 may move axially somewhat due to the flexing of springs 49 when the annular coil or clutch actuating coil 31 is energized. Energizing coil 31 draws clutch plate 51 axially toward side surface 53 of pulley 15 frictionally to engage surface 53 thereby connecting rotatable member 55 to compressor crank shaft 23.
- coil 31 is deenergized, for example, by a manual or thermostatic control (not shown)
- clutch plate 51 under the influence of springs 49 returns to its rest position and no longer frictionally engages surface 53. In this rest position compressor 19 is inactive, however, rotatable member 55 free wheels about the axis 33 on a bearing 57. .Iadd.Bearing 57 is supported on portion 58 of clutch plate 51 shown in FIG. 3. .Iaddend.
- Rotatable member 55 includes not only pulley 15, but also bearing retainer spring 59, and generator rotor portion 63, which includes flywheel 65 and a series of permanent magnets 67, which together form a multipole rotor for the alternator.
- Flywheel 65 may have the permanent magnets 67 adhesively bonded to its interior rim. Flywheel 65 and its permanent magnets 67 are again concentric within reasonable limits with axis 33.
- Flywheel 63 may be provided with a plurality of air passing apertures 69 for cooling the generator stator portion.
- a cooling fan may be mounted on member 65 to force air through holes 69 for applications in which the vehicles main cooling fan is not favorably located with respect to this alternator.
- the air passing apertures have webs lying therebetween and these web portions may be bent to form a fan type structure.
- Axial space saving is accomplished by the nesting of generator and compressor portions which is most readily seen in FIG. 3.
- generator elements such as the permanent magnets 67 and stator 25, including stator laminations 27 and windings 29, are nested with and overlap somewhat magnetic clutch actuating coil 31 as well as bearing 57 and shaft engaging member 39.
- a substantial space saving and weight saving over merely an end to end connection of a generator and compressor is thereby achieved. It will be understood that electromagnets energized through slip rings on member 39 may be substituted for permanent magnets 67.
- FIG. 4 illustrates another manner in which the windings may be connected and which connection may be preferred in some vehicle environments.
- the three windings 29 are Delta connected with each winding junction, such as 71 coupled by way of a diode 73 to the positive terminal of storage battery 75.
- Voltage regulating circuit 77 may sense the voltage across the battery and provide appropriate gating signals to silicon controlled rectifiers, such as 79, so as to pass or block charging current, depending upon the state of charge of the battery 75.
- a fan blade 80 is supported on a shaft 82 connected to a pump 84 such as a vehicle water pump having an impeller 87.
- Frame 84 of the water pump supports stator laminations 86 having windings 88 disposed therein.
- a pulley 90 is engine driven and in turn drives a flywheel 92 supporting permanent magnets 94 to provide a generator or alternator operating substantially as previously described. Mounting the alternator directly behind the vehicle cooling fan in this manner allows excellent cooling of the alternator windings, silicon controlled rectifiers and diodes.
- the alternator rotor is common with the vehicle fan and water pump shaft.
- the illustrated preferred embodiment is of an alternator.Iadd.-.Iaddend.compressor, however, pumps found in vehicles other than air conditioner compressor pump might equally well be integrated with an alternator, or other type generator advantageously according to the principles of the present invention.
- a bracket may support the alternator when no compressor is present. Accordingly, the scope of the present invention is to be measured only by that of the appended claims.
